Case Study: Windshield De-icing Hex mesh: 283,000 cells Tet mesh: 317,000 cells Hybrid mesh (prism + tet): 54,000 cells 34
Case Study: Windshield De-icing • Comparison in terms of the percentage of the windshield surface cleared of ice – Note the time needed to melt 90% of the windshield surface – The prediction using hex mesh is considered as a reference prediction. • The coarse hybrid mesh gives a reasonable prediction with much fewer cells. • Pure tet mesh overpredicts the melting by ~10% 35
